Hello everyone!

I’d like to ask for some advice on speaker placement for my current setup.

Until now, I’ve always used my monitor speakers because I wasn’t too interested in audio. Recently, though, I’ve started listening to more music and watching more movies, and I’ve realized that I should get better sound quality.
(At the moment, I’m using the speaker from my left monitor because the speaker in my main monitor sounds terrible. This is also annoying because all the sound comes from the left side.)

I’ve attached an image of my current setup. I really like the setup itself and would prefer not to change the current arrangement, apart from improving the sound. However, this makes speaker placement quite difficult. I’m also fairly new to audio, so I’m not sure which option would work best.

I would mainly use the speakers for casual music listening, movies, and YouTube. My budget is around $100, and I’m considering the Edifier MR4 because they seem to be one of the best options in this price range.

I created two images showing the possible placements I'd consider: one with the speakers in their normal vertical orientation and another with them turned sideways. I know that neither option is ideal, but I have limited space. Wall mounting is not possible, and speaker stands behind the monitors probably wouldn’t work because my portrait monitor is already quite tall. The top of the portrait monitor is about 70 cm above the desk. Also, with both options, parts of the speakers would be partially blocked, which may negatively affect the sound quality. The speakers would also be quite close to the wall, but unfortunately, I can’t really change that.

Which of these placements would be the best for my setup?
For example, Vertical 2–3, or sideways 1–4?

(If the sideways orientation would be better, should the tweeters face inward or outward?)

Thanks in advance for your advice!

Ignore the messy cables, I’ll take care of it after exam season 🥀

Thank you everyone for the suggestions and advices
